Hypotension during intermittent hemodialysis is common, and has been attributed to acute volume shifts, shifts in osmolarity, electrolyte imbalance, temperature changes, altered vasoregulation, and sheer hypovolemia. Although hypovolemia may intuitively seem a likely cause for hypotension in intensive care patients, its role in the pathogenesis of intradialytic hypotension may be overestimated.

Imbalance band market is an alternative to traditional structures which proposed ensure that system frequency remains within acceptable bounds. In imbalance environment, the load-serving entities (LSEs) can purchase bands or reduce load deviation by operating a battery energy storage (BESS) avoid penalty for causing imbalance. The concept would be effective in sharing balancing responsibility b...

BACKGROUND Two main theoretical models have been used to assess the impact of psychosocial work factors on blood pressure (BP): the demand-control model (DC) and the effort-reward imbalance (ERI) model. Little is known about their independent and combined effect. OBJECTIVE To examine the independent and combined effect of the DC and ERI models on ambulatory BP (ABP). METHOD Data were collec...

Background: Sagittal imbalance is known as the main radiographic driver of disability in adult spinal deformity (ASD).In this study, the association of radiological spinopelvic parameters and clinical outcomes was evaluated following thecorrective surgery of sagittal imbalance, in order to explore the predictive ability of each parameter.Methods: A total of 23 patients, who underwent corrective...
